Title: Filing and sawing machine
IPC: B23D67/00
Filed: 1954-11-11
Abstract: 787,849. Sawing: vices. BARKER, R. V. Nov. 4, 1955 [Nov. 11, 1954], No. 27338/54. Classes 61 and 145. [Also in Group XXII] A sawing and filing machine comprises a frame 13 in which the saw, file 20 or the like is held, a source of power 14 for reciprocating the tool and means 7 for moving the frame 13 transversely. The electric motor 14, frame 13 and a housing 15 in which the frame reciprocates on guide-rods 17 are mounted as a unit on a horizontal pivot 12 carried by a support 10 angularly and vertically adjustable on a post 9 mounted on a carriage 6. A screw 28, supported in a cap 29 on the post 9 and rotatable by a handle 30, adjusts the platform 10 which is locked by a lever 11. The carriage 6, traversed by the handturned lead-screw 7, is guided by bars 4, 5, Fig. 3, extending between the legs 1 of a mounting which also presents a horizontal surface 27 for co-operation with an adjustable stop 25 carried by the housing 15. A flat surface 31 on the frame 13, for a spirit level or a protractor and a spirit level, facilitates adjustment of the stop 25 which has a screw-threaded cap 26 to effect fine adjustments. The motor 14 drives the frame 13 through gearing, including a worm-gear in an oil bath, a crank-disc 23 and an adjustable connecting rod 22, and a knob 24 on the motor shaft enables small movements of the frame to be made. The work, in a clamp or vice provided with holes in one jaw to receive horizontally-slidable pins supporting the work during clamping, is located in relation to the mounting by a scribing point fixed in one of the collets 19 of the frame 13 and used as a datum set by stop.25 resting on the surface 27. The rear surface of one of the jaws of the vice may be parallel to the lead-screw to facilitate adjustment for angular cuts. The saw frame may be weighted and extra pressure applied by a handle 33. A stop (not shown) may prevent the frame falling after the work has been cut.

Title: Graphite body
IPC: C04B35/532
Filed: 1965-08-05
Abstract: A graphite body having a relatively high and substantially isotropic coefficient of thermal expansion is produced by maintaining a petroleum residue above its melting point, contacting the residue with a free oxygen-containing gas until the melting point of the residue is raised to at least 150 DEG  C., coking the treated residue at 450 DEG  to 650 DEG  C., calcining the resulting coke at 900 DEG to 1500 DEG  C., comminuting the calcined coke, admixing the comminuted coke with a carbonizable aromatic binder, forming the admixture into a desired shape, carbonizing the binder in the shaped body in an inert atmosphere and graphitizing the body at 2600 DEG  to 3000 DEG  C. in an inert atmosphere.  The "petroleum residue" consists of the residues from the vacuum or atmospheric distillation of crude oil and the free oxygen-containing gas may be air, which may be blown through the residue at 30 to 50 s.c.f. per minute per ton of residue, which may be agitated and maintained at 260 DEG  to 300 DEG C.  Preferably the blowing treatment is continued until the melting point of the residue is at least 225 DEG  C., the coking is carried out at 450 DEG  to 525 DEG  C. and the binder is carbonized at 750 DEG  to 1000 DEG  C.  Oxygen, oxygen-enriched air or a mixture of oxygen and argon are other suitable gases.  Coal tar pitch, petroleum pitch and wood pitch are suitable binders.ALSO:A graphite body having a relatively high and substantially isotropic coefficient of thermal expansion is produced by maintaining a petroleum residue above its melting point, contacting the residue with a free oxygen-containing gas until the melting point of the residue is raised to at least 150 DEG  C., coking the treated residue at 450 to 650 DEG  C., calcining the resulting coke at 900 DEG  to 1500 DEG  C., comminuting the calcined coke, admixing the comminuted coke with a carbonizable aromatic binder, forming the resulting admixture into a desired shape, carbonizing the resulting binder in the shaped body in an inert atmosphere and graphitizing the body at 2600 DEG  to 3000 DEG C. in an inert atmosphere.

Title: Improvements in and relating to electric temperature and fire alarm systems
Inventor: GJERKEN HAAKON
IPC: G08B17/06
Filed: 1960-10-03
Abstract: 937,813. Electric temperature alarm systems. GJERKEN ELEKTRO A.S. Oct. 3, 1960, No. 33813/60. Class 118. In an alarm system two loops 17, 18 at a local station (Fig. 2) are connected in parallel across a D.C. source at a central station (Fig. 3), temperature sensitive means 10 at the local station connecting the first loop to the second loop via a resistor 16 at a first order of temperature rise about the normal ambient temperature, whereupon an indication is given at the central station; and connecting the loops directly together at a second order of temperature rise, whereupon an alarm is given at the central station. Temperature increases cause the level of the mercury 11 in flask 10 (Fig. 1), to rise, connecting wire 12 first to wire 14 and then to wire 15, wire 12 being connected to loop 17 and wire 15 to loop 18 (Fig. 2). The positive terminal of the D.C. source is connected via relay 21 (Fig. 3), a back contact of relay 24, 17A, 17B and the winding of relay 23 to the negative terminal, relay 21 (high resistance) being normally operated. The positive terminal is also connected via a back contact of relay 24, 18B, 18A, a front contact of the normally-operated relay 22 and its winding, and a front contact of relay 21 to the negative terminal. When the means 10 connects loop 17 to loop 18 via resistor 16 the extra current flowing in relay 23 brings up that relay, thus lighting the indicator lamp 40. Direct connection between the loops results in the release of relay 21 which brings up relay 25, thus lighting fire-indication lamp 46 and operating the alarm relay 26, which locks-up until released by operation of re-set switch 44. Fault operation.-Open-circuiting of either loop results in the release of relay 22, which completes an alternative circuit for relays 21 and 23 in parallel with loop 17, (so that relay 21 re-operates), and connects positive to terminal 18A. Connections between loops 17 and 18 effected by the means 10 are thus effective as before. The release of relay 22 also lights the fault lamp 54. Short-circuit conditions release relay 21 and bring up 23, relay 24 also coming up to light the indicator lamp 61. Melting point contacts 19 (Fig. 2), then initiate the fire alarm by releasing relay 23 to bring up relay 25. Speech facilities.-Change-over switches at the central station may connect a microphone to the loops in place of the relay equipment, loud-speakers being connected in series with capacitors between the loops at the local station.

Abstract: 521,643. Electric incandescent lamps. MAYER, H. Nov. 22, 1938, No. 33955. [Class 39 (ii)] A lamp filament is formed by twisting together two similar wires which are then coiled into a helix of the same sense or hand as the twisting. The pitch of the twist and the helix dimensions are such that each turn of the helix comprises one or more complete twists or an aliquot part of a twist. The helix may be bent into a further coil of such diameter that, in the case where each turn of the helix comprises a single twist, the distance a between turns of the coil is constant. Twisting stresses in the individual wires are avoided during twisting by arranging that the reels from which the wires are drawn are free to turn on their axes. A single wire filament may be connected in series or parallel with the twisted filment.
